VPN Versus Zero Trust for Growing Businesses

VPN Versus Zero Trust for Growing Businesses

A new starter needs access to a cloud finance system from home. A contractor needs one application for a two-week project. A sales manager connects from hotel Wi-Fi. These routine requests expose the practical difference in the VPN versus zero trust discussion: should users be admitted to the company network first, or verified for the specific resource they need?

For many small and growing businesses, a virtual private network remains a sensible part of secure remote working. It is familiar, cost-effective and often already built into the firewall. Zero trust offers a more precise model for controlling access, particularly where cloud services, remote staff and external partners are central to daily operations. The right answer is rarely a simple replacement. It depends on your systems, risk profile and ability to manage access consistently.

What a VPN does well

A VPN creates an encrypted connection between a user’s device and the business network. Once connected and authenticated, the user can typically access internal resources much as if they were in the office. That could include a file server, line-of-business application, database or remote desktop environment.

Its principal advantage is straightforwardness. If your organisation relies on on-premises systems that cannot easily be published securely to the internet, a VPN provides a protected route in. It can be especially useful for a small team that needs secure access to a limited number of systems and has a well-managed set of company devices.

VPNs also encrypt traffic over untrusted networks. That matters when employees work from home, use shared workspaces or travel. A properly configured VPN, protected by multi-factor authentication, is far safer than exposing an internal service directly online.

However, a VPN connection can grant broad network-level access. This does not mean every VPN is inherently unsafe, but it does mean permissions need careful design. If one compromised account or unmanaged laptop gains a route into the network, an attacker may have more room to move than the user actually requires for their job.

VPN versus zero trust: the fundamental difference

Zero trust is a security approach rather than one single product. Its principle is simple: do not trust a user, device or connection merely because it is inside the network or has used the correct password once. Verify each access request using relevant context, then grant only the minimum access required.

A zero trust approach can assess several signals before permitting access. These commonly include the user’s identity, multi-factor authentication status, device health, location, unusual sign-in behaviour and the sensitivity of the requested application or data. Access can be restricted to a single application rather than the wider network.

For example, a payroll contractor may be allowed to use the payroll platform during agreed hours from a managed device, without being able to browse shared folders, reach servers or see other business applications. If their device is no longer compliant with security updates or encryption requirements, access can be blocked until it is remediated.

The distinction is therefore about the access boundary. A traditional VPN often secures the route into a network. Zero trust concentrates on securing identity, device posture and the individual resource being requested. Modern VPN platforms can adopt zero trust-style controls, while a zero trust programme may still use a VPN for specific legacy systems. These are not always competing technologies.

Where zero trust delivers stronger business protection

Zero trust becomes particularly valuable when an organisation has moved beyond a single office network. Cloud software, hybrid work and outsourced specialists have made the traditional network perimeter less relevant. Business data may sit across Microsoft 365, cloud storage, SaaS platforms and hosted infrastructure, accessed from many locations.

In this environment, broad network access is often unnecessary. Restricting people to the exact applications and data they need reduces the potential impact of stolen credentials. It also supports clearer accountability: access logs can show who used a particular system, from which device and under what conditions.

This model supports a more reliable offboarding process as well. When an employee leaves, their identity and assigned access can be removed centrally, rather than relying on someone to remember every VPN group, shared folder and separate application account. For growing businesses, this discipline prevents security controls from falling behind operational change.

Zero trust can also improve the user experience when it is implemented well. Employees may access approved cloud applications directly after strong authentication, without manually connecting to a VPN or routing all traffic through the office. Yet that benefit depends on thoughtful configuration. Poorly planned conditional access rules can block legitimate work and create frustration for staff.

The trade-offs to plan for

A VPN is usually quicker to deploy for a contained requirement. It can be the practical choice where staff need remote access to older internal applications, budgets are limited and the network is segmented appropriately. It does not remove the need for patching, endpoint protection, strong passwords, multi-factor authentication and active monitoring.

Zero trust takes more design effort. Your business must understand its users, devices, applications and data. Identity management becomes central, as do accurate joiner, mover and leaver processes. Conditional access policies should be tested carefully, especially for senior staff, mobile workers, service accounts and third-party suppliers.

There can also be cost and complexity considerations. Licensing, endpoint management and specialist configuration may be required. A small business does not need to implement every zero trust capability at once, but it does need ownership. Security policies that are never reviewed can become either too permissive or too restrictive.

The greatest risk is treating either model as a set-and-forget purchase. A VPN left with weak authentication or unrestricted access creates exposure. Zero trust deployed as a collection of overly complex rules can lead users to seek workarounds. Technology must reflect how people actually work, while protecting the systems that keep the business running.

Choosing the right approach for your business

Start with the systems your people need to access and the consequences if those systems were compromised. If most staff use cloud applications and only a few administrators need internal network access, application-level zero trust controls may be the better long-term direction. If a core legacy system remains on site and requires network connectivity, a tightly controlled VPN may remain necessary.

Consider device ownership too. Company-managed laptops with encryption, security updates and endpoint protection provide stronger assurance than personal devices. Where bring-your-own-device access is unavoidable, limiting access to browser-based applications or managed app containers can reduce risk compared with granting full network connectivity.

Your access model should also reflect the people involved. Permanent employees, temporary workers, administrators and external providers should not receive identical permissions. Administrative accounts deserve additional controls, such as separate privileged identities, stronger authentication requirements and closer monitoring. A ransomware incident often begins with a valid account, so reducing unnecessary access is a direct continuity measure.

For many organisations, the sensible route is phased. First, enforce multi-factor authentication across critical services. Next, identify and remove unnecessary accounts and permissions. Then introduce device compliance requirements and conditional access for high-risk applications. Retain a VPN where it is genuinely needed, but segment the network and limit VPN users to the resources relevant to their role.

Questions to ask before changing remote access

Before selecting a platform or changing a policy, establish whether you can answer these operational questions clearly:

  • Which applications and data are essential to daily operations?
  • Who needs access to each resource, including suppliers and contractors?
  • Are all devices encrypted, patched and protected against malware?
  • Can access be removed promptly when someone changes role or leaves?
  • Do you have logs and alerts that will identify unusual sign-ins or access attempts?

These questions may sound basic, but they reveal where security and day-to-day IT management are disconnected. The aim is not to add barriers for their own sake. It is to make secure access repeatable, visible and proportionate to the risk.

A managed IT partner can help assess the current environment, map access requirements and introduce improvements without disrupting essential work. At URBlink, that means looking beyond the remote-access tool itself to the surrounding controls: identity, devices, backups, firewall rules, monitoring and a tested response plan.

The most useful next step is not choosing a label. Review one high-value business system, identify exactly who should use it and verify that access remains protected when a password, device or location cannot be trusted. That practical exercise often makes the right path clear.
